Aluminum ash is produced in all processes where aluminum is melted. It is a hazardous waste. The content of aluminum accounts for about 1-12% of the total loss in the aluminum production process. And because the scope of aluminum application in various industries is also increasing, as the main by-product of the aluminum industry, the amount of aluminum dust produced is also increasing.
However, because aluminum ash contains a large number of toxic elements, if it is not treated, directly landfilled or stacked, it will cause great harm to the environment and does not meet the requirements of our country's sustainable development policy. Therefore, in this case, how to turn aluminum ash into waste and realize the comprehensive utilization of aluminum ash while avoiding other hazardous waste in the process of aluminum ash processing and utilization has become a problem that we must solve.
For the processing and processing of aluminum ash, we can use a crusher to pulverize the agglomerated aluminum ash into a qualified fineness, add various ingredients, mix uniformly, and produce industrially usable aluminum-containing oxides or aluminum-containing salts through roasting. Or, the main harmful elements nitrogen, chlorine, and fluorine in aluminum ash can be removed by washing, roasting, etc., to obtain harmless aluminum ash for reprocessing to achieve the purpose of harmless treatment.
Henan Zhengzhou Mining Machinery Co., Ltd. is committed to the research and development of process technology and complete set of process equipment for the treatment of aluminum ash hazardous waste, and has a complete solution for the harmless and resource-based treatment of aluminum ash.
